Advantages and disadvantages of piano lacquered furniture

The "piano paint" on this book belongs to the surface post-treatment process after plastic molding, but it must be subdivided in the general sense of the piano paint belongs to a kind of paint baking process, which is to primer and then bake paint - spray paint - then paint film and then carry out the process of high temperature fixed phone, to achieve this process honestly 5k This book is impossible to use this process, because the cost is too high. The disadvantage is that it is fragile, that is, there will be cracks on the surface, and the so-called piano paint that everyone is exposed to is actually polyurethane paint, which is directly painted without spraying primer and then UV curing, the principle is the same as ultraviolet curing glue, the only advantage over piano paint is the cost, as long as the paint is sent to the ultraviolet lamp for 5 seconds. From the appearance, there is no difference with piano paint, but there will be no cracks when you knock it, because the polyurethane paint is very tough, but due to the lack of stability, it will turn yellow and discolored for a long time, which is the biggest difference with piano paint, as for fingerprints or something, it is actually related to color, black is the easiest to show fingerprints, white is not easy, this is the characteristics of the paint process, not a disadvantage, because the glass will also have fingerprints when touched, and the frosted process is quite a cheap process, As long as the electric spark treatment on the mold is OK, there is no need to grind and polish, and because the surface is rough, no matter the color adhesion and hand-held friction are very sufficient, the disadvantage is that frosting is a low-grade symbol, especially in the handicraft industry.
